SSRL Beam Port Schedule

X-ray beam lines are scheduled in three 8-hour shifts each day (11pm-7am; 7am-3pm; 3-11pm). Checkouts/changeovers are scheduled during the 7am-3pm shift. Most X-ray beam lines officially turn over to the next user much earlier than 3pm depending on the equipment requirements and staff availability. At least 1 week prior to arrival, users need to contact the designated beam line engineer/scientist (see SSRL Beam Lines by Number for contact information) to discuss beam line configuration needs and start times. Unless instructed otherwise, experiments end at 7am (6am when Maintenance (MA) or Accelerator Physics (AP) are scheduled).
